How can I track a button click from a different UI?

阅读更多关于 How can I track a button click from a different UI?

问题 I'm sorry if this question isn't framed the way it should, I have trouble wording out my problem. Is it possible to see which button the user clicked, if the button was on a different UI? I have a GSP page that is displaying a Jenkins Blue Ocean to monitor a pipeline. I want to track if the user has pressed any pause or abort buttons, but because the Jenkins Blue Ocean isn't part of my page, I can't send anything to my controller. Would there be any work arounds or methods to track something

【推荐阅读】微服务还能火多久？>>> 1.不生成 version 字段 static mapping = { version false } 2.分页结果集列表 PagedResultList，非常适合分页查询 def c = Account.createCriteria() def results = c.list (max: 50, offset: 10) { like("holderFirstName", "Fred%") and { between("balance", 500, 1000) eq("branch", "London") } order("holderLastName", "desc") } println "Rendering ${results.size()} Accounts of ${results.totalCount}" results.size() 为返回的 list 记录大小，上面为offset为10的50条记录 results.totalCount 为符合条件记录在数据库大小 3.使用proxy() 方法获取关联Domain class Book{ Author author } def author=Author.proxy(1) //不会到数据去查询实际数据 Book.findByAuthor(author) author只是补助作用

2020年九大java开发框架，小编主要介绍Spring框架、Hibernate框架、Struts框架、Play框架、GoogleWebToolkit框架、Grails框架、Blade框架、JavaServerFaces框架、Vaadin框架九大框架，希望您可以多java框架有更多的认识。一、Spring框架　　Spring框架框架排名首位，具有开发复杂Web应用程序的出色能力，这些应用程序因性能突出而广受赞誉。使Java开发人员能够轻松地创建企业级应用程序。Web应用程序开发人员可以证明Spring框架的能力。是Spring成为Java开发人员最爱的原因。在开发人员的选择中，SpringMVC和SpringBoot远远领先于其他Java技术。对于开发人员来说，这里的一大优势是他们可以不受其他模块约束而专注于一个模块，因为Spring利用了控制反转（IoC）。其他优点是一个全面的配置模型，支持传统数据库和现代数据库（如NoSQL），并通过支持面向方面编程来支持内聚开发。提供一些模块如SpringMVC、SpringCore、SpringBoot、SpringTransaction等。二、Hibernate框架　　作为一个对象关系映射（ORM）数据库，改变了我们以前查看数据库的方式。尽管不是一个全栈框架，但可以极其轻松地为多个数据库转换数据。支持多个数据库的能力使很容易扩展
